I think I have it. Plane two will have the higher KE since KE is quadrupled with increase in speed. The weight is a factor but not as much as speed. Thanks
Homework Statement
Which has a higher kinetic energy?
An airplane traveling at the speed of sound or an airplane with half the weight of plane one and traveling at 2 times the speed of sound?Homework Equations
KE = 1/2 mv^2
v=gtThe Attempt at a Solution
I think I am just get mixed up on words...
